Definitions

  • the invention relates to a strip storage for a continuous operation of rolling mills, in particular a loop-forming strip storage for sheet metal strips in strip processing systems, consisting of a sling carriage that can be moved on guides in the sense of a sling change with at least one deflection roller for a sling and with the sling carriage by tension members such as ropes, chains or The like connected, with at least one support roller for the tape also movable on guides, as well as with at least one feed roller and a discharge roller for the tape.
  • Strip storage for rolled strips is required in order to be able to operate the rolling stands in rolling mills continuously, even if individual bundles that have to be connected to one another before being introduced into the rolling stand are to be fed to the rolling mill or rolling stand and rolled by the latter.
  • a loop storage device and a loop former of some form must be provided, which in its Kapa is designed such that the strip can be fed continuously to the roll stand or rolling mill even when the individual bundles are prepared or welded together.
  • Kapa is designed such that the strip can be fed continuously to the roll stand or rolling mill even when the individual bundles are prepared or welded together.
  • the same considerations apply to other plants processing the metal strips, for example pickling plants or annealing furnaces that are operated continuously and in which the different incoming strip speeds have to be compensated.
  • sling towers, sling pits or horizontal sling pullers are used.
  • Horizontal loop pullers or horizontally arranged tape storage devices are known from the printed prior art, in particular from DE-OS 1 953 169, AT-PS 299 103 and from European patent application 0 110 864.
  • the horizontal loop puller according to DE-OS 1 953 169 for tape processing systems with loop car and idlers is characterized in that the idlers are mounted in several so-called followers movable in the horizontal direction.
  • the ropes connecting the trailer and the sling carriage are wound on rope drums and are kept constantly tensioned by the drive of the rope drums. Since the sling car pushes the follower in front of it in the sense of shortening the supply sling, the restoring force via the cable drum drives only has the task of keeping the connecting cables taut, so that the following followers are only moved by the sling car when the rope length between the sling wagon and the following successor is used up. If the cable drum is driven by a spring drum, the springs only have a short service life of a few months. Is the rope running? mel drive electric, each motor must have its own control and its own energy supply. Both are disadvantageous.
  • the horizontal strip storage for sheet metal strips according to AT-PS 299 103 contains a movable loop carriage, which can preferably be driven with a constant torque in the sense of a loop enlargement, and several support carriages which can be moved along guide rails.
  • An endless rope, which is guided around pulleys, is connected to the sling carriage and the support carriage. From this rope, the drive for the support car is derived via take-off rollers with the interposition of reduction gears in such a way that the support cars are at the same distance from one another when the sling car moves.
  • a particular disadvantage of this tape storage device can be seen in the fact that a different transmission ratio is necessary for each car and that a high risk of contamination of the drive pinion and the rack does not lead to exact drive and transmission ratios.
  • the horizontal belt store according to EP-OS 0 110 864 also shows a movable loop carriage to which individual support carriages are coupled with the aid of flexible tension members which can be pulled out against a restoring force.
  • These tension members should be elastically stretchable at least in some areas. They are designed, for example, as rubber ropes or the like and are looped around deflection rollers. This training is intended to effect a bumpless drive of the support car from the loop car while maintaining a uniform distance between the individual support cars.
  • the disadvantage of this tape storage is that the flexible or elastic rubber ropes age relatively quickly and become brittle and therefore uncontrolled and at different speeds can wear and that rubber ropes can be easily damaged in the rough rolling mill environment, so that there is also a risk of tearing the rubber ropes.
  • the band store of the type mentioned is characterized by a cam drum arranged at least on each support carriage and interacting with a torque resistor, on the drum jacket of which the tension member runs.
  • the advantages of the band storage device according to the invention are that both during filling and when emptying the storage device, the sheet metal strip is optimally and continuously carried by the support rollers of the support carts, that no jolting load is transferred to the support carts when moving the sling car, and that the use is highly resilient Steel cables, the arrangement of the cam drum and the preferred use of a torque motor lead to a very high reliability of the system.
  • the torque motor can be designed to be relatively small, since it only has to overcome the frictional moments. Even when the sling carriage is retracted, the support carriages keep the same as one another due to the inventive measures Distances.
  • the combination of a torque motor and a cam drum results in a cable pull that is directly proportional to the cable length.
  • the further embodiment of the invention shows a curved drum with an increasing contour, on which the tension member is wound or unwound during a sling carriage movement.
  • a contour preferably a conical drum
  • the cam drum consists of a short cylindrical section with a subsequently rising drum contour.
  • the conical part of the drum should preferably have a diameter ratio of 1: 3 to 1: 3.5.
  • the conical drum contour has helically screwed-in cable grooves, so that an exact guidance of the traction cable on the cone is ensured, whereby the predetermined distances between the support carriages are ensured during the process. It is expedient here if the drum contour is surrounded at a distance by a suitably designed hood, the traction cable running between the drum contour and the hood.
  • An exact cable guide on the cam drum can also be achieved in that the cam drum is gearingly connected to a guide device for the traction cable to be guided on the drum contour. Rope displacements, rope entanglements or a rope running over one another on the cam drum are avoided with great certainty.
  • the measures described above enable the support carriages to be spaced precisely and very reliably with each other, so that the strip storage works robustly and maintenance-free even in the most difficult operating conditions in the rolling mill.
  • the torque motor and the cam drum connected to it are arranged in the area of the subframe of the support carriage, preferably at the level of the wheel axles of the support carriage, the torque motor making electrical contact with a current-carrying rail arranged in the foundation and between the wheel guides or with a cable garland Has.
  • the cam drum and the torque motor are expediently to be arranged in the middle of the axis, so that the support carriages have the lowest possible lateral forces during the movement.
  • the belt store 1 consists of a loop carriage 2 which is moved on rails 4 by a motor-driven winch 3.
  • the sling carriage 2 carries a deflection roller 5.
  • a feed roller 6 or a discharge roller 7 for the sheet metal strip 8 to be stored is provided.
  • the support car 9 have wheels 14 which run on the rails 4.
  • a cam drum 15 with a torque motor 16 is arranged in the area of the subframe 29 of each support carriage 9, the torque motor being in contact with a busbar 17 which is arranged between the guide rails 4 in the foundation 18.
  • the torque motor 16 can also receive the power supply via a cable garland, not shown.
  • the cam drum 15 connected to the torque motor 16 - the exemplary embodiment according to FIG. 3 shows a cone 21 - has cable grooves 19 in which a traction cable 20 runs, which forms the connection between loop car 2 and support car 9 and between the support car 9 with one another .
  • the cam drum consists of a short cylindrical drum section 22 with the subsequently rising cone 21.
  • the cable grooves 19 are screwed into the cone 21 in a helical manner.
  • the cone is surrounded by a correspondingly designed hood 24 at a distance, the traction cable 20 running between the cone and hood.
  • the cam drum can be connected in a geared manner with the aid of a toothing 25 and a pinion 26 with a helically grooved pinion shaft 27 to a guide device 28 for the pull rope 20 in order to guide the pull rope on the cone 21 as precisely as possible. This can be done, for example, by providing the guide device 28 with an inner groove corresponding to the pinion shaft 27, so that the guide device is displaced by predetermined paths when the cam drum rotates or when the pinion shaft 27 rotates becomes.
  • the storage of the cam drum and pinion shaft can be carried out with the usual means in practice and is not shown for the sake of simplicity.
  • the support carriage 9 and the loop carriage 2 are moved together in the area of the feed roller 6 and the discharge roller 7, respectively.
  • the connecting traction cable 20 is completely wound on the cone 21 for each individual support carriage.
  • the motor-driven cable winch 3 pulls the sling carriage 2 against the braking torque of the torque motors 16 onto the cable winch.
  • the traction cable 20 is unwound from each cam drum by certain amounts, which correspond to the travel path of the individual support carriages 9. Since the torque motors 16 are designed in the same way for all support carriages, all support carriages 9 are pulled out against the same braking torque, so that large distances between the support carriages 9 form with respect to the respective travel point of the loop carriage. A cable length-dependent cable pull is thus achieved.
  • the sling wagon 2 is moved back, whereby the connecting cable between the sling wagon 2 and the support wagon 9 is relieved.
  • the relaxed and shortening pull rope 20 is wound onto the drum contour 23 by such amounts that the distance between the loop carriage 2 and the support carriage 9 decreases.
  • the relief of the traction cable between the sling car and the support car also leads to a relief of the connecting pull cable between each support car 9.
  • the relieved and shortening traction cables between the support carriages wound up by the individual curve drums In this way, the same distance is always set between the loop carriage 2 and the next support car 9 and between the support car 9 when the tape store is emptied, depending on the respective position of the loop car.
